-->-- '''Marge Simpson''' after hearing Bart whistle The Simpsons theme song while coming into the kitchen, ''WesternAnimation/TheSimpsons''

* In ''AFunnyThingHappenedOnTheWayToTheForum'', the characters of Senex and Hysterium sing or hum the songs "Everybody Ought to Have a Maid" and "I'm Calm" at a various points. The first one's a plot point, as Senex mistakes Philia for a new maid (read: concubine), prompting the song. He sings it later while taking a bath, unintentionally leading Erronius to [[IncrediblyLamePun erroneously]] believe that his house is haunted.

* An issue of ''ComicBook/{{Daredevil}}'' has a child singing the theme song to ''WesternAnimation/AvengersEarthsMightiestHeroes''.

** A later issue of ''Avengers Assemble'' reveals that SpiderWoman has it as her ringtone. In the final issue, Captain America has it downloaded to Anya/Spider-Girl's phone. The last panel is of her dancing to it.

* One of the first times {{Deadpool}} breaks the FourthWall is when on his way to fight TheHulk he starts singing the theme song from the {{Series}} ''TheIncredibleHulk''.

* In the first episode of the early-1980s Public Radio serialization of ''StarWars'', the famous Main Title fades down and is filtered to become -- the background music of a commercial for the Imperial Merchant Marine Corps to which Luke is listening.
* In StanFreberg's ''Franchise/{{Dragnet}}'' spoof "Little Blue Riding Hood," Granny's doorbell plays the ''Dragnet'' theme. (For this and its A-side "St. George And The Dragonet," the orchestra used was the actual ''Dragnet'' orchestra, as Jack Webb loved the idea!)

* One episode of ''TheNavyLark'' has Sub-Lieutenant Phillips whistling the show's theme music as a "Ditty" he'd picked up somewhere. He's promptly told to stop it by the rest of the cast as it [[BitingTheHandHumor sounds silly and annoying]].

* The ending credits music of ''SuburbanKnights'' can be heard over the stoner's radio in the first scene.

Not the same thing as TitleThemeDrop, which is when a title theme is also used in the context of the work itself such as if a remix of the title theme plays when fighting the final boss of a video game, though there may be some overlap at times, if both are used within the same work. Basically, if a character hums the theme tune, a band plays it or it's on a ringtone or something -- if it's diegetic-- then it's this trope. If the theme song plays as the soundtrack over the episode, then it's a TitleThemeDrop. If the ''lyrics'' of the theme tune (or any other song) are used in dialogue, it's WaxingLyrical. See also ThemeSongPowerUp.

* In Act II of ''DoctorHorriblesSingAlongBlog'', the Doctor's cellphone ringtone is the first two bars of the Bad Horse theme.

* While ''TheIncredibles'' doesn't have a proper theme song, the most-repeated motif from the score is called "Mr. Incredible's Theme". Bob Parr can be heard humming this melody when he returns home after a night of clandestine superheroing. In addition, one of the DVD {{Easter Egg}}s shows Mr. Incredible dancing to a swing version of the theme.

* At the beginning of George Michael's "Faith" video, "I Want Your Sex" is playing on a jukebox (the very first image of the video). Interestingly enough, upon release "Sex" was used less to advertise the "Faith" album (released in October, as opposed to this song's June) than the recently new film [[BeverlyHillsCop ''Beverly Hills Cop II'']].
* LimpBizkit's "Rollin'" video began with Ben Stiller and Stephen Dorff pulling up to Fred Durst-- while their car's radio plays "My Generation" (the band's previous single, not the Who song).
* [[JasonDerulo "Whatcha Say"]] can be heard at the start of the "In My Head" video, either coming from a car radio or the speakers of the convenience store whose parking lot is the video's location.

* In ''ComicBook/TheSmurfs'' comic book story "Bathing Smurfs", Handy is heard singing ''WesternAnimation/TheSmurfs'' theme tune as he returns to the village from his hiking trip, with the words superimposed on a music scale.

* In one of the [[ComicBook/AmalgamUniverse Amalgamverse]] comics following the Marvel vs. DC crossover, Spider-Boy also sings his own version of the song.

* Similarly, Spider-Boy, the Comicbook/AmalgamUniverse version of Spider-Man crossed with Comicbook/{{Superboy}} sings a theme song about how {{Toyetic}} he is:
-->"Spider-Boy! Spider-Boy! Has the very best action toys! Top ten show, game and vid! Gotta love the Arach-Kid!"

** A later issue of ''Avengers Assemble'' reveals that SpiderWoman has it as her ringtone.
** Captain America has it downloaded to Spider-Girl's phone

* Similarly, Spider-Boy, the Comicbook/AmalgamComics version of Spider-Man crossed with Comicbook/[{Superboy}} has a theme song about how {{Toyetic}} he is:

** A later issue of ''Avengers Assemble'' reveals that SpiderWoman has it as her ringtone.

** Although it's not quite the same principle (being more a case of RecycledSoundtrack), in one episode the tune "March of the Oysters" from ''Series/{{Stingray 1964}}'' can be heard emanating from a man's house

* Disney/TheHunchbackOfNotreDame the melody of "The Bells of Notre-Dame" is played many times throughout the sound track, including in other songs. The tune to "Hellfire" is heard throughout too.

* In the ''Manga/SailorMoon'' stage musicals, better known as the ''SeraMyu'', the characters sometimes perform stageshows within the musical itself. One musical has the Senshi, in civilian form, preform ''La Soldier'' as part of Rehersal, considered the ''SeraMyu'''s theme by the fans (it appears in nearly every musical either as part of it or an encore number), only to have a character complain they'll be recognized by the baddies for singing it. Moments later the baddies show up in {{Paper Thin Disguise}}s and preform their version of La Soldier (sung by the children in the group). Said scene can be found [[http://www.youtube.com/watch?v=Y4dw3avLc_A here]].

* Used as a MythologyGag in episode eight of the ''TheJokerBlogs'': Joker hums his theme tune from the animated series while [[spoiler: escaping from Arkham Asylum.]]
